此外，我还使用lib和struts-html.tld中的所有jar文件。请...请帮助我... !!

    将commons-beanutils jar添加到您的类路径可以解决此问题。

    您没有在动作映射..in struts-config.xml中添加输入。input = \“ / insert.jsp \” 尝试这个 
    < action path=\"/insert\" type=\"com.cac.struts.InsertAction\" 
        name=\"insertForm\" scope=\"request\" validate=\"false\" input=\"/insert.jsp\">
    好

    可能您先在web.xml中输入了条目，然后又添加了所需的jar，尤其是commons-beanutils.jar。只需删除web.xml的内容并重写它们即可。

    您错过了
    web.xml
    中的映射，应该是这样的： 
    <web-app>
    <servlet>
        <servlet-name>one</servlet-name>
        <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
        <init-param>
            <param-name>config</param-name>
            <param-value>/WEB-INF/struts-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>one</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
</web-app>
    还要将
    struts-config.html
    重命名为
    struts-config.xml
    。
